HOW-TO Chainsaw Carburetor Rebuild - Jonsered 2071

[@donyboy73]

ALWAYS USE HIGH OCTANE FUEL WITH NO ETHANOL TO PREVENT DAMAGE AND COSTLY CARBURETOR REPAIRS ON YOUR OUTDOOR POWER EQUIPMENT!

[@5roundsrapid263]

My uncle had a small engine shop when I was young. It's good to see there are still honest mechanics like him around. Merci, Don!

[@HallNeedsaRose1]

Well, after your help getting my Stihl ms250 back running ( breakdown to replace impulse line) I just pulled out my dust covered Jonsered 450 thats been sitting in my cellar for decades and getting ready to tackle getting it back running. I found a new love in small engine breakdown and repair thanks to your help. I also have a Toro lawnmower thats been sitting in my back yard for decades also that I just put on the list but for a beginner I can't get too excited and just do 1 thing at a time. I am going to subscribe and get a free education on small engines. You've already saved me money on work I have been paying that a fix it shop to do. Thank you very much Doctor.

[@alanbaker6965]

Just followed your video for rebuilding the carb on my Jonsered 2065. My carb is Zama, but parts and procedure were exactly like the Walbro. Excellent concise how to video, many thanks. Now to reinstall and hope it runs better. This was my virgin rebuild and somehow the metering valve and spring slip into place on the first try.🎉 Your video is what the internet should be used for, good stuff! So glad I came across your site😊

Don you're my canadian friend. For anybody who's not canadian wouldn't understand. 🇨🇦👍

[@joepruneda2263]

sir from man to man I gotta tell u I love u you just saved me some money again u are the definition of THE BEST.

[@fadetounforgiven]

Nicely explained. I also have a Jonsered but I can't remember the model (and now I'm about 100 miles away from it, so I can't go and look it up), but what I do remember is that I have to service it and doing this looked a bit daunting to me, even when I've serviced other things at home, carburetor rebuilds included. Now, even if it's not the exact same model, which it's not since the choke is on the other side (and it doesn't disengage automatically), it doesn't look that hard. Thank you, the way you explained things really help.

[@tonym6920]

Great video Dony, as always! Your video quality and attention to detail is the best I've ever seen in repair videos. I always learn a lot watching your videos Dony, thanks! Have a great weekend!

[@donyboy73]

[@semco72057]

I enjoyed watching how you replaced the carburetor kit and adjusted the saw. My two saws have been to a shop too many times and especially my Stihl chainsaw, which is the newest. I have had problems with them starting and running and the Stihl is the worst. I started it two days ago to test it, and it started and ran until I was sure it would work, then turned it off, and put it away. Today I attempted the same with my Poulan, but it didn't start at all. I may have flooded it, and will try starting it again tomorrow to see if it will start, and then check the Stihl saw also. The Poulan gave me the best service though, and I am tired of taking them to the shop each season to get them running. I did that last season, and my neighbor just helped me go get my two lawn mowers going, and it didn't cost me a fortune to do it.

[@TR-ut3yh]

Thank you for the informative video. I recently inherited my fathers Jonsered 52e and it hasnt been serviced in years. Sadly, I never learned how to rebuild a carb from him before he passed but im going to try it after watching your video.

[@darrelrhame9351]

My wife say's you have created a monster(meaning me..lol). Since watching your videos I have repaired a small crack @ the oil drain plug, rebuilt the carb and replaced the head gasket on my 97 Murray 12.5 hp riding mower(runs better than ever). I also found and replaced the leaking shaft seal on my 5.0 hp Murray pushmower and rebuilt carb on that, I am currently working on a Jonsored 2050e chainsaw and have 2 yardman pushmowers to rebuild and an old Snapper Hi-Vac ridingmower to work on, you think if I take up all the room in the garage (she can barley get her car in now) I might be able to get me a bonafide shop to work in for my new hobby and my old hobby which is blacksmithing. Your videos have definitely been a game changer for me, anybody that repairs mowers around here has a 6 month back up.

[@robthebank9453]

Thank you very much for this video!! I was able to rebuild mine easily with your help!

[@99carnot]

Nice to see this procedure. Inlet valve spring is important:) Good tip on cutting off a bit of the fuel line when reconnecting it. Thanks and have a good weekend!

[@johnclarke6647]

I am so old I remember sae30w in chainsaws. the oldest two cycle oil I still have is an oil named Staymix, which I used to by at my stihl dealer in Fitzgerald, ga. it was good oil and I used a ton of it through the years, usually at 40:1 in my Husqvarna and Poulan saws. back then, we were not to finicky about which oil we used - only that we mixed it properly. now we have to be very clinical with every tank of two cycle gas we make. I use nothing but stihl Ultra oil in all my two cycle gas and the oil is measured, exactly, at 2.6 ounces per gallon of premium non-ethanol gas. in the old days I just dumped the one gallon can of two cycle oil it in the gas can and pumped one gallon, more or less, of regular gas in the can

[@zx8401ztv]

Nice to see an older unit that hasnt been messed with, and it starts and runs much happier now :-D.

[@mikespain8655]

We live in a disposable society. When something breaks or doesn't work right, people just throw it away and buy a new one. I like fixing equipment that is still good just needs some tlc. There is a certain satisfaction to it, and you have history with it. Plus I like learning new things and overcoming a challenge. It ain't brain surgery.

[@zx8401ztv]

I was born into a family with very little money, so learning to repair things was the norm, and i would not have it any other way :-). Most of my electronic test gear is second hand, and ive had to repair it, i appreciate it more too :-D

[@unisol2287]

Every day we're going to learn something new until we retire, thanks donny!

[@chrisdowing1775]

Geez, I wish all the carbs I work on looked that clean! Good job!

You do such informative video thank you retired timber faller just still in the blood can't get enough chain saws!

[@donyboy73]

thanks fred

[@fitzyholden1036]

Nice simple carb to rebuild. Thanks for that mate.

[@KristerKristiansson]

Hi great video, in the Husqvarna factory we were not allowed to snip of the fuleline like that. We had to use a pair of scissors, just the same type you use to cut dog's claws... else the rubber could crack and might eventually slip off.

[@donyboy73]

good tip, thanks

[@charger19691]

Nice rebuild Don and these saws look like they hold up pretty well! Fast revving engine too.

[@johnsmith-sw7ii]

Years ago tools called for different fuel to oil ratios. I have an old Sears Craftsman leaf blower / vac that calls for 16 to one. Still runs great!

I have a jonsered 2054 turbo whith no oil to the chain. I have cleaned the lines and had a look at the pump that seems Nice. But suspect the drive wheel/gear to the pump that has failed but it looks like a "springgear" how does it work?

[@ΝίκοςΟρφανίδης-ο2δ]

Hello dony .I have this moto ! I would try to change the turns of carburettor! But I cant .Please tell me how many turns can I do from start because moto cant start now !!Thank you

[@donyboy73]

start at 1 1/2 turns out then tweak from there

[@brwadabrown43]

Very good explanation. If I have a Jonsered 630, would the carburetor removal be about the same? Thanks.

[@ambharbor]

great video Don. thanks for your sharing.

[@Jamesmaynard66]

Excellent video, Makes me think I'll give it a go. Well done.

[@blaknift]

Why in the world was walbro using JIS screws on the metering cover and hold down for the needle pin?

[@aesthetic_mfr]

Nice eye

[@williamharrington828]

Great video, I have a homelite chainsaw that will not fire could it be a bad ignition coil ?

[@Adam-bw4lw]

did you check for spark ?

[@williamharrington828]

Yes, I took the plug out put the coil wire on the plug ground it on the motor pulled the cord I get no spark to the plug so I'm thinking it's a bad ignition coil the engine seems to have compression so I don't think it's the valves but I'M no expert on chainsaws

[@Adam-bw4lw]

probably a bad coill...btw 2 stroke engines dont have valves

[@williamharrington828]

See I told you I didn't know much about chainsaws LOL , good at working on lawn mowers but not chainsaws ,Thanks for the info

[@danielpadgett2831]

Dony I just had a question I have a Stihl leave blower it boggs when you try to give it full throttle for just a second or so even after it warms up do I adjust the H screw or the L screw about a quarter turn? It's a BG 56.

[@waynechavarillo8585]

Great video that really helps me with my chainsaw thank you.

Great video as always Dony.

[@pippaengroda]

My dad used to have on of these, i always liked that is said "turbo" on it ^^

[@peterford9369]

Hi Donnie, I noticed when you placed gaskets and diaphragm s, on one side diaphragm went on first then gasket, but other side is reversed. Is that proper or does it matter? Thanks,, good video .

[@mat7247]

I have the same saw. My carb says HD 6 751. Im having trouble finding a carb kit for the HD-6. Do you know of the part number?

[@jumperg1]

I bought new John Deere d130 lawn tractor last fall only put 10 hrs on it, this year when I started it the engine surges. They tell me carb must be cleaned, any suggestions? Do I have to take carb apart?

[@evanchapmanfanman]

I worked on a 2050 turbo which looks very similar although it is slightly larger, have you ever had one of these in with a broken recoil housing? The one I had the entire cover had broken away.

[@donyboy73]

yes I have

[@evanchapmanfanman]

donyboy73 it’s really unfortunate as these are actually pretty nice saws but that simple issue causes these to be thrown out or donated. The one I fixed was for a pawn shop.

[@glenngressley3345]

thanks, i would be curious on what the difference is on the funcitions of the 2 diaphrams. i thought the black rubbery type one was the fuel pump. keep up the good work.

[@SuperJamster1]

Donny, I've always fixed carbs with floats/needles. Does the movement of the diaphragm going in and out, work the same as the float lifting and dropping? If so, how does the movement occur with no fluid to lift the diaphragm? Pressure?

[@G0J0]

Pressure from the impulse line is what in told

[@Tdmill]

I have a vintage Jonsereds 70E I Think. I purchased it used in 1981 and have used it faithfully through the summer of 2017. I am hoping to keep it alive. It needs a piston kit. After breaking mine down, I saw that the piston has two rings. Everything I see for the 70E K model has one ring in the piston. I need some help in locating the correct kit. Can you help? Thanks in advance, Tom

Any video on carb on an Echo 33018" by chance?

[@jaynegus4526]

I live down here in the U.S. in Connecticut. I am very lucky to have access to gasoline with ZERO Ethanol close by in New York state only 30 minutes away. I just installed a new carb. kit for the carb in my Stihl BG85 hand held blower - I bought the blower brand new and have never run it on gasoline containing ethanol - it is 12 years old and the carb components were 100% original. For everyone reading this comment - Try to use gasoline that does not contain Ethanol - it is amazing how destructive ethanol is !

[@danielrobert7181]

So true ! Ethanol will absorb moisture like crazy. No problem in your car where you go through the fuel tank in less than a week but most chainsaws or small motor appliances might very well be left with gaz standing for months. Avoid that crap at all costs !

[@cliffordmacdonald4748]

hi have a 1999 350 husqvarna chain saw that has been sitting for a long time it won,t start its getting spark but seems to be flooding out what should i do

It'd be hilarious for Dony to drop a chooch here and there. I've been waiting but he's pretty good. He may come from a slightly more posh family than Chris. I don't judge, I just speculate.

I don't recommend using a typical carb cleaner- I used some on my echo CS600p carb and destroyed (or swelled) the internal seals. Whatever it destroyed was non serviceable- had to buy a new carb.
